Root canal therapy is a routine dental procedure, performed millions of times each year, that helps preserve natural teeth and avoid more complex replacement options. By treating the source of infection inside the tooth, this procedure can relieve pain and restore function while maintaining your smile.

Inside every tooth is a soft tissue called the pulp, which contains nerves and blood vessels essential during tooth development. When the pulp becomes inflamed or infected—often due to deep decay, repeated dental work, cracks, chips, or trauma—it can cause significant discomfort. Common warning signs include tooth pain, prolonged sensitivity to hot or cold, swelling in the gums or face, or visible injury to the tooth. If these symptoms appear, your dentist may recommend endodontic treatment to remove the infection and protect the tooth from further damage.
